I hope you know the concept of quadratic equations, since you are gonna need it for this question.

anonymous · Answer

I do, but none of them have yielded a correct answer. Just need some clarification on where I;ve gone wrong, perhaps.

parthkohli · Answer

What you will do in this is that, you'd subtract 8 from both sides and then solve the quadratic equation.

anonymous · Answer

Oh, now I see it. Had a wrong negative, thank you.
